The figure shows a normal distribution with mean m and standard deviation d, including approximate percents of the distribution in each of the six regions shown. For a population of 800,000 subway riders, the numbers of subway trips taken per rider last January are approximately normally distributed with a mean of 56 trips and a standard deviation of 13 trips. Approximately how many of the riders took between 30 and 43 trips last January? A 60,000 B 110,000 C 160,000 D 210,000 E 270,000 Drawing a picture of the the distribution table will solve this.Answer by edjones(7569)   (Show Source): You can put this solution on YOUR website!, z=(30-56)/13=-26/13=-2 z=(43-56)/13=-13/13=-1 Area under the normal curve between z=-2 and z=-1 is 0.136 800,000 * 0.136 = 108,800 B .
